IPC: H01J1/304
Filed: 1995-05-17
Abstract: PURPOSE: To provide a structure effective in improving and uniformizing electron emitting characteristics of a field emission type electron emitting element, and its manufacturing method. CONSTITUTION: A comb-shaped or wedge-shaped emitter 32 is worked from a single crystal silicon thin film by using an SOI board composed of a single crystal silicon thin film, a silicon oxide layer 34 and a silicon board 31, and the silicon oxide layer is removed, and the exposed silicon board is formed as an anode 33. Voltage is impressed between the emitter and the anode, and an electron is emitted from the emitter. Since a distance between the emitter and the anode is determined by a thickness of the silicon oxide layer, uniformity and controllability are improved. When a digging-down part is arranged in an anode part, an electric field is concentracted in the upper end corner, 3nd electron emitting voltage is further uniformized. The single crystal silicon thin film opposed to the emitter can be used as an anode.

Title: Interface circuit
Inventor: FURUHATA MAKOTO
IPC: H03K19/018
Filed: 1983-07-01
Abstract: PURPOSE:To increase the driving ability of a linear amplifier without increasing the area of the emitter of a transistor (TR) constituting an I<2>L circuit by connecting a current mirror circuit for amplifying small current between the I<2>L circuit and the linear amplifier. CONSTITUTION:When +VCC is supplied from a +VCC power supply to the 3rd terminal, a constant current circuit CS11 is actuated and the I<2>L circuit 11 is also actuated. When the 1st terminal is turned to the L level by an input signal V1, a TR Q12 in the circuit 11 is turned off and then output current I0 from a TR Q15 flows into a diode D12 and a resistor R11. The diode D12 and the TR Q16 constitute the current mirror circuit and current corresponding to the output current I0 flows through the +VCC power supply, a TR Q16 and a resistor R12. Consequently, the sum IX of both of the current becomes a current value obtained by multiplying the current I0 by R11/R12. The driving property of a TR Q21 is increased by the current value and the TR Q12 drives only the current I0, so that it is unnecessary to increase the area of the emitter.

Title: Circuit module
Inventor: KAWAGUCHI YOSHITO
IPC: H05K3/36
Filed: 1990-05-08
Abstract: PURPOSE:To obtain a circuit module which does not induce pattern burn-out due to stress in assembly, etc., by providing a pattern which is to related to a signal line at a flexible printed-circuit board and that which is hot related to the signal line at a printed-circuit board of a circuit module opposing it, and then soldering the patterns. CONSTITUTION:Corresponding signal lines of signal line patterns 3 are soldered on a printed-circuit board 1 and a flexible circuit board 2. Further, patterns 4 which are not related to the signal line are also soldered. The patterns which are not related to the signal line are located at an inside from a part which is exposed form a protection film 5 of the signal line pattern 3. When the flexible printed-circuit board 2 is soldered onto the printed-circuit board 1, soldering of the signal line pattern is made at an inside from the printed-circuit board end face as compared with soldering of a pattern which is not related to the signal line. Therefore, if a stress is applied in a direction for releasing the flexible printed-circuit board 2 from the printed-circuit board 1, stress is applied to a part to be soldered of the pattern 4 which is not related to the signal line and no stress is applied to the part to be soldered of the signal line pattern 3.

Title: Key input circuit
Inventor: FUJII TAKASHI
IPC: H03K17/00
Filed: 1987-05-14
Abstract: PURPOSE:To reduce power consumption, by providing a means which controls the gate potential of a first P-channel MOS transistor and that of a second P-channel MOS transistor arbitrarily, and the means which controls the gate potential of a first N-channel MOS transistor and that of a second N-channel MOS transistor arbitrarily. CONSTITUTION:When a key 1 is depressed and a phi1 is set at (1), the P-channel transistor 8 and the N-channel transistor 9 are turned ON, and the drains of the transistors 8 and 9 are short-circuited. The current consumption at that time is decided by the bias voltage of the gate of the transistor 8. The gate potential of the transistor 8 is decided by a bias voltage supplying circuit consisting of transistors 26-28. In such a case, the current consumption in a key input circuit is suppressed at a minimum level compared with the current consumption in a conventional key input circuit. Also, in the key input circuit, it is necessary to consider about a current consumed by the bias circuit, however, it is possible to suppress the current at a negligible level.

Title: Parameter missetting preventing system
Inventor: KUKI EIJIROU
IPC: G05B15/02
Filed: 1979-09-14
Abstract: PURPOSE: To prevent the missetting of the parameter, by inhibiting the setting of the parameter until both the item number and the data value of the parameter stored are displayed for confirmation.  
     CONSTITUTION: The item number is set to the item number setter 1 for the parameter to be set, and then the display button 7 is pushed. Thus the CPU4 displays the item number and the data value designated each to the item number display unit 5 and the parameter display unit 6 respectively. With this display, both the item number and the data value can be confirmed. The comparator 9 delivers the coincidence signal when a coincidence is obtained between the item number displayed  and the set item number, and then gives the signal to the AND circuit 8. Then the  data value of the parameter to be set is set to the parameter setter 2, and then the  setting button 3 is pushed. As a result, the interruption signal is sent to the CPU4  via the circuit 8 to carry out the rewriting of the data. In such way, the missetting  can be prevented.

Abstract: PURPOSE: To enable, by a simple constitution, detection of the water level in a container or whether or not there is a container, by providing a light receiving part at the side of the container and above a heater for receiving a beam generated by a change in water quantity inside the container, and by controlling the introduction of electric current into the heater on the basis of a signal from the light receiving part. CONSTITUTION: A siphon-shaped lower container 3 to be heated by a heater 2 is to store water for heating, while an upper container 4 to be fitted on the lower container 3 includes a water passing pipe 5 to be inserted into the lower container 3. The water inside the lower container 3, when heated, is gradually passed through the water passing pipe 5 by the vapor pressure inside the lower container 3 and pushed into the upper container 4, thereby lowering the water level of the lower container 3. When the water level becomes lower than a detection line connecting a light emitting part 8 and the light receiving part 9, the light passing through the lower container 3 stops passing through the water, the voltage between the emitter and the collector of a phototransistor becomes lower than the applied voltage, and the introduction of electric current into the heater 2 is stopped.
